Can I point you towards the Medals & Orders Research Society (I think its called) and to a book publisher called John Mussel. He might be able to offer you ideas for a search for the medals.
In the last case you would be able to acquire copy medals and have them mounted (court style of course). You are entitled to wear your father's medals (real or copy) but as others will tell you, you wear them on the right side of your coat or whatever. If the cost is too steep, get a set of miniatures.
